Thanks again for the replies with this - I have tried a donor MAF (an old XJ6 S3 unit - the correct Lucas Model, sadly with an incorrect diameter of exit chamber so it was only really useful for voltages) and i'm getting an identical reading using both MAFs - 1.6v. I'm assuming that turning the...

Thanks for the replies - the butterly is set correctly, I did this when the plenum was off so that's ok. I suspect it's misfueling as there is helluva stink of petrol and clouds - literally - of the usual smoke when it's running. I actually flooded it trying to get it to run, it's pulling so...

Hey all, just fitted the plenum back onto the v8 having had it off to clean it and rejig the throttle stop; it had fallen back in too far and the butterfly was jamming closed, and the thing is running like a heap of nonsense - I can barely get it to idle and it's smoking like a boss from...

Thank you all very much for your responses up to now: I stripped down the vacuum hoses and had a cursory look at them all; no sign of any holes but the rubber looked a bit perished around the joins so I clipped them and resealed. The upshot is, she's idling ok so far, no nonsense when i was...

Thanks a lot, I appreciate that. Is the third the vacuum advance? If so, what does it do?

Updates: First start in exactly 2 weeks, started on the button, idled fine for 10 minutes then back to the irratic lumpy idle as described above, albeit not as violent as before and no stalling. I'm going to strip the top tomorrow and take the throttle body off; in the meantime, any ideas...

Thanks a lot for your help Pete, that's interesting to know there's no IAC valve and also explains why I can't find it :rolleyes: I'm going to tackle it on Tuesday; I'll take the plenum off and have a good clean around...I'll report back with pictures and updates. Thanks again!

Hey folks, I have recently returned from Glastonbury with the Classic ('89 3.5 efi, 41k miles) and at the start of the journey, the old girl was playing up as soon as she warmed up: the idle was all over the place and I was having to left foot brake to stop her from stalling. This lasted for...

Cheers dogs, I'll have a wee gander around at the weekend - there is a jag breaker over motherwell way and I'm sure he's mentioned something about LR before...

Hi Folks, Just acquired my first Rangie at the weekend - Beluga Black 89 3.5 EFI Vogue SE - I am absolutely delighted! The thing has so much character it's unreal, and is a fantastically capable beast for something that's older than me! I've given her a good wash and a polish (which took 3...
